Pierisin, a protein purified from pupae of the cabbage butterfly, Pieris rapae, exhibits cytotoxic effects against the human gastric cancer TMK-1 cell line, inducing apoptosis. The present study was performed to determine whether pierisin might exert a similar influence on nine other human cancer
The Small Cabbage White ( Pieris rapae) is originally a Eurasian butterfly. Being accidentally introduced into North America, Australia, and New Zealand a century or more ago, it spread throughout the continents and rapidly established as one of the most abundant butterfly species. Although it is a
The cabbage butterfly Pieris rapae contains a strong apoptosis-inducing substance, pierisin, against human cancer cell lines, which is thought to act via ADP-ribosylation. Here we report the purification and cloning of an apoptosis-inducing substance, designated as pierisin-2, from another cabbage
Crude extracts from larvae, pupae and adults of cabbage white butterflies, Pieris rapae and Pieris brassicae, and green-veined butterfly, Pieris napi, have an ability to induce apoptosis in the human cancer cell lines. As apoptosis inducing protein, pierisin-1 and -2 have been isolated from pupae of
Pierisin-1, present in cabbage butterfly, Pieris rapae, induces apoptosis against various kinds of cancer cell lines. Another cabbage butterfly, Pieris brassicae, also has an apoptosis-inducing protein, Pierisin-2. These proteins exhibit DNA ADP-ribosylating activity. Pierisin-like proteins are
Pierisin-5 is a DNA dependent ADP ribosyltransferase (ADRT) protein from the larvae of Indian cabbage white butterfly, Pieris canidia. Interestingly, Pierisin-5 ADP-ribosylates the DNA as a substrate, but not the protein and subsequently persuades apoptotic cell death in human cancer cells.
Cabbage butterflies, Pieris rapae and Pieris brassicae, contain strong cytotoxic proteins, designated as pierisin-1 and -2, against cancer cell lines. These proteins exhibit DNA ADP-ribosylating activity. To determine the distribution of substances with cytotoxicity and DNA ADP-ribosylating activity
In this study, caspase-dependent apoptosis-inducing pierisin-5 gene was identified and characterized from cabbage white butterfly, Pieris canidia. A thousand-fold increase in expression of pierisin-5 gene was observed from second to third instar larvae, gradually decreasing before pupation.
We have previously reported that the cabbage butterfly, Pieris rapae, contains a 98-kDa protein, named pierisin, that induces apoptosis in a variety of human cancer cell lines. In the present study, sequencing and cloning of a cDNA encoding pierisin was accomplished. PCR-direct sequencing showed
ADP-ribosyltransferases transfer the ADP-ribose moiety of βNAD+ to an acceptor molecule, usually a protein that modulates the function of the acceptor. Pierisin-1 is an ADP-ribosyltransferase from the cabbage butterfly Pieris rapae and is composed of N-terminal catalytic and C-terminal ricin B-like
The 6th European Antibody Congress (EAC), organized by Terrapinn Ltd., was held in Geneva, Switzerland, which was also the location of the 4th and 5th EAC. As was the case in 2008 and 2009, the EAC was again the largest antibody congress held in Europe, drawing nearly 250 delegates in 2010. Numerous
